8V19N882NVGI8

Overview

The Renesas 8V19N882NVGI8 is a high-performance clock jitter attenuator and synthesizer within the FemtoClock NG family. It generates high-frequency clocks and low-frequency synchronization signals (SYSREF) from an internal Voltage-Controlled Oscillator (VCO). The device supports output frequencies ranging from 0.192 MHz to 6 GHz with LVDS and LVPECL output types. It accepts input frequencies up to 2 GHz and operates on a single 3.3 V supply. Key features include integrated signal delay modules for phase alignment, automatic lock detection, and four selectable clock switching modes for redundancy. Configuration is managed via a 3/4-wire SPI interface.

Feature Summary

• Generates outputs from 0.192 MHz to 6 GHz using an internal VCO
• Accepts input frequencies up to 2 GHz with spread spectrum support
• Includes integrated signal delay modules for precise phase alignment
• Supports LVDS and LVPECL output levels

Applications

• JESD204B/C interface clocking for data converters
• High-speed serial communication systems
• Test and measurement equipment requiring low-jitter clocks
• Telecommunications infrastructure

Procurement Notes

Verify the specific suffix 'NVGI8' against official Renesas documentation to confirm package type, temperature range, and tape/reel specifications. Ensure compatibility with system power requirements and SPI configuration protocols before procurement.

Selection Notes

Select this component when ultra-low jitter performance and flexible frequency synthesis are required for high-speed digital interfaces. Confirm that the 3.3 V supply voltage aligns with the system design and that the VFQFPN-76 package fits the PCB layout constraints.

Part Context

This part belongs to the Renesas 8V19N882 series of FemtoClock NG devices. These components are designed for applications demanding superior clock integrity and flexibility, often replacing discrete clock generation solutions in complex electronic systems.

Replacement Considerations

Consult Renesas official cross-reference tools for verified substitutes. Generic clock generators may not match the specific jitter attenuation or SYSREF synchronization capabilities of this model.
